RECORDING MEDIUM APPARATUS AND CONTROLLER

摘要

A memory unit (601g) of a recording medium apparatus (600g) memorizes a content and a nullification list. The nullification list, associated with the content, is assigned to a device related to the use of the content, and includes a nullification identifier for identifying a nullified public key certificate. A controller (602g) of the recording medium apparatus (600g) is provided with: an acquisition unit (621g) for acquiring an acquisition request for a content from a device (300g), and acquiring a device identifier that identifies the public key certificate of the device (300g); a determination unit (622g) for determining whether or not the device identifier matches a nullification identifier; and a control unit (623g) for controlling so that outputting of the content to the device is prohibited when the match is determined.
